decided to do new thread to avoid confusion.
ascan, even though is powerfull tool, needs to be called multiple times in most of the uses because there are more than one matches and all need to be found.
I would thus suggest that aScan() would be enhanced to return optionally array of the results.
so:
$array="some","words","and","some","more"
$matches = ascan($array,"some",...,1) ;last argument, return all occurences
for each $match in $matches
$match ","
next
would result in "0,3"

4) Added an option to AScan to return all matching elements.
The 'Mode' parameter of AScan now takes a bitpattern as input with the
following possible values:
bit 0 0 = search for exact match (default) 1 - do an instr() scan
bit 1 0 = return first matching element 1 - return all elements
Examples:
AScan( $Array, $String,,, 0) ; scan for exact match and return 1st hit
AScan( $Array, $String,,, 1) ; use InStr() and return 1st hit
AScan( $Array, $String,,, 2) ; scan for exact match and return all hits
AScan( $Array, $String,,, 3) ; use InStr() and return all hits
